通过对不完全投影重建的图像结果和正弦图对投影空间的数据分布情况进行分析，并根据工件较敏感部位的位置、形状和密度信息，对缺失的投影数据进行适当的补充。在此基础上，利用滤波反投影算法对补充后的正弦图进行图像的重建。经过实验验证，该方法改善了重建图像的质量，得到了较好的重建效果。

The results which was gotten incomplete projection reconstruction by sinagram,could analysis the distribution cha-racteristics in space of projection data.According to the sensitive parts of the object position,shape and density information, this paper made the appropriate supplement on the projection data.And then it reconstructed the last image utilizing the whole projection by filter back projection algorithm.Through the experiment,this method can obtain better image reconstruction results.
